Europe's Coldest Cities in Summer. Europe's northernmost city has the continent's coolest summers. No other major city stays anywhere as tepid as ReykjavÃ­k, Iceland, where maximum temperatures average a meagre 12.7 degrees Celsius (54.8 degrees Fahrenheit). That's over five degrees Celsius (10 Â°F) lower than the next coldest city, Leeds.
While the weather in the UK has similar temperature swings, snow is rare and winters in England are full of rain and fog. The best time to visit France, the UK and Germany is in late summer (August and September) when the weather is warm and there is little rainfall. Further south the temperatures are much more constant, and countries on the Mediterranean coast have much milder conditions. The weather in Italy, Greece, Portugal and Southern France and Spain is warm and sunny, with rainfall in the spring and autumn.
